近日,全球范围内首次采用转炉-连铸-热轧全流程工艺路线生产的超高强度、高延伸率TWIP1180HR钢在鞍钢下线。在节能环保的大背景下,轻量化是未来汽车发展的方向,高强钢成为汽车产业绿色发展的首选材料。为此,强度和塑性兼顾,具有更高延伸率的新一代经济型先进高强钢成为世界各大钢铁企业的研究热点。TWIP钢,又称
Recently, the world’s first ultra-high-strength, high-elongation TWIP1180HR steel produced by the converter-continuous casting-hot-rolling process has been put out of production at Ansteel. In the context of energy saving and environmental protection, lightweight is the future direction of the development of automobiles, high strength steel to become the preferred material for the green development of the automotive industry. To this end, both strength and plasticity, with a higher rate of elongation of a new generation of advanced high-strength steel economy has become the world’s major steel companies research hot spots. TWIP steel, also known as
